BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an imaging device, particularly animaging device that displays an image, a display control method, and aprogram that executes the method in a computer.

2. Description of the Related Art

Recently, an imaging device such as a digital still camera or a digitalvideo camera (e.g., a recorder equipped with a camera) has beenpropagated which images a subject such as a person or an animal tocreate image data and records the image data as image content.Furthermore, an imaging device has been suggested which can confirm theimage content by displaying an image becoming a recording target on adisplay portion at the time of the end of an imaging operation(so-called review display).

Furthermore, an imaging device exists which creates a plurality ofimages by a series of imaging operations, relates the plurality ofcreated images to each other, and records the images. For example, animaging device exists which relates the plurality of images created by acontinuous imaging to each other and records the images. When theplurality of recorded images is reproduced in this manner, for example,a representative image to be set in a continuous imaging unit isdisplayed in a list and a desired representative image among therepresentative images displayed in a list is selected. Moreover, aplurality of images corresponding to the selected representative imagecan be displayed.

For example, an image display device is suggested in which a displaysize of each continuous image is adjusted depending on the number of thecontinuous image becoming the target of the list display and theplurality of continuous images is displayed in a list by the displaysize after the adjustment (e.g., see Japanese Unexamined PatentApplication Publication No. 2009-296380 (FIG. 6)).

SUMMARY OF THE INVENTION

According to the aforementioned related art, since the plurality ofcontinuous images is displayed in a list by the display size after theadjustment, each of the continuous images can concurrently be displayedin a list.

Herein, a case is supposed where an imaging operation is performed usingan imaging device which relates and records a plurality of imagescreated by a series of imaging operations. In a case of performing aseries of imaging operations using the imaging device, after the end ofthe imaging operation, when the plurality of images created by theimaging operation is confirmed, it is considered that at least a part ofthe respective images is review-displayed.

Herein, for example, when the imaging is performed at a touristattraction by a traveler, since each person moves, an imaging timing isimportant. For this reason, it is important to rapidly confirm acomposition thereof and a desired subject after the end of a series ofimaging operations. Thus, for example, in regard to a plurality ofimages created by the imaging operation, since the image processing isperformed according to the imaging sequence and the recoding processingis performed, after the end of the imaging operation, it is decided toreview-display an initially created image.

However, when the reproduction of the plurality of images created by theseries of imaging operations is instructed, a user selects a desiredrepresentative image from the representative images displayed in a listin many cases. For this reason, when an image to be review-displayed forconfirmation after the end of the imaging operation is different fromthe representative image, the image confirmed during the imagingoperation is different from the image viewed as a selection targetduring reproduction, whereby an incompatibility may occur in theselection target image at the time of the reproduction.

Thus, it is desirable to easily confirm a representative image of aplurality of images after an imaging operation when a plurality ofimages is created by a series of imaging operations.

According to one embodiment, the disclosure is directed to an imageprocessing apparatus that includes an image acquiring unit that acquiresa plurality of images, a processing unit that creates a plurality ofcomposite images having a sequential relationship based on apredetermined rule using at least a portion of each of the acquiredimages, and selects a representative image corresponding to theplurality of composite images.

According to the embodiment of the invention, a superior effect isobtained in which, when a plurality of images is created by a series ofimaging operations, a representative image of the plurality of imagescan easily be confirmed after the imaging operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, embodiments (hereinafter, referred to as embodiment) forcarrying out the invention will be described.

The description will be made in the following order:

1. First Embodiment (display control: an example that displays arepresentative image and state of progress notification informationafter an imaging operation of a multi-view is finished)2. Second Embodiment (display control: an example that sequentiallyreview-displays a representative image candidate of a multi-view imagedepending on a change in posture of a device to determine arepresentative image)

1. First Embodiment Configuration Example of Imaging Device

FIG. 1 is a block diagram that shows an inner configuration of animaging device 100 in a first embodiment of the invention. The imagingdevice 100 includes an imaging portion 110, a gyro sensor 115, aresolution conversion portion 120, and an image compression expansionportion 130. Furthermore, the imaging device 100 includes a ROM (ReadOnly Memory) 140, a RAM (Random Access Memory) 150, and a CPU (CentralProcessing Unit) 160. Furthermore, the imaging device 100 includes a LCD(Liquid Crystal Display) controller 171, a LCD 172, an input controlportion 181, an operation portion 182, a removable media controller 191,and a removable media 192. In addition, an exchange performed betweenthe respective portions constituting the imaging device 100 is performedvia a bus 101. The imaging device 100, for example, images a subject tocreate a plurality of image data (captured images) and can be realizedby a digital still camera capable of performing various image processingin regard to the plurality of image data.

The imaging portion 110 converts an incident light from the subject tocreate the image data (captured images) based on the control of the CPU160, and supplies the created image data to the RAM 150. Specifically,the imaging portion 110 includes an optical unit 112 (shown in FIG. 7),an imaging element 111 (shown in FIG. 7), and a signal processingportion (not shown). The optical unit includes a plurality of lens (azoom lens, a focus lens or the like) which concentrates light from thesubject, and light from the subject incident via the lens and an iris issupplied to the imaging element. In addition, an optical image of thesubject, which was incident via the optical unit, is imaged on animaging surface of the imaging element, and the imaging element performsthe imaging processing in this state, thereby outputting the imagingsignal to the signal processing portion. Moreover, the signal processingportion performs the signal processing with respect to the imagingsignal, whereby the image data is created, and the created image data issequentially supplied to the RAM 150 and is temporarily maintained. Inaddition, as the imaging element, for example, a CCD (Charge CoupledDevice) sensor, CMOS (Complementary Metal Oxide Semiconductor) sensor orthe like can be used.

The gyro sensor 115 detects an angular velocity of the imaging device100 and outputs the detected angular velocity to the CPU 160. Inaddition, an acceleration, a movement, a tilt or the like of the imagingdevice 100 may be detected using another sensor (e.g., an acceleratorsensor) other than the gyro sensor, and the CPU 160 can detect a changein posture of the imaging device 100 based on the detection result.

The resolution conversion portion 120 converts various input image datato the resolution suitable for various image processing based on thecontrol signal from the CPU 160.

The image compression expansion portion 130 compresses or expandsvarious input image data depending on various image processing based onthe control signal from the CPU 160. The image compression expansionportion 130, for example, compresses or expands various input image datato JPEG (Joint Photographic Experts Group) type of image data.

The ROM 140 is a read dedicated memory and stores various controlprograms or the like.

The RAM 150 is a memory used in a main memory (a main memory unit) ofthe CPU 160, includes a working area or the like of the program executedin the CPU 160, and temporarily stores the program or the data necessaryfor performing various processing by the CPU 160. Furthermore, the RAM150 includes an image conservation area for various image processing.

The CPU 160 controls the respective portions of the imaging device 100based on various control programs stored in the ROM 140. Moreover, theCPU 160 controls the respective portions of the imaging device 100 basedon an operation input or the like received by the operation portion 182.

The LCD controller 171 displays various image data on a LCD 172 based onthe control signal from the CPU 160.

The LCD 172 is a display portion that displays the image correspondingto various image data supplied from the LCD controller 171. The LCD 172,for example, sequentially displays the captured image corresponding tothe image data created by the imaging portion 110 (so-called monitoringdisplay). Furthermore, the LCD 172, for example, displays the imagecorresponding to the image file stored in the removable media 192.Instead of the LCD 172, a display panel, for example, an organic EL(Electro Luminescence) panel or the like may be used. Furthermore, asthe display panel, a touch panel may be used by which a user can performthe operation input of the intent thereof by contacting or approaching adisplay surface with fingers.

The input control portion 181 performs the control relating to theoperation input received by the operation portion 182 based on theinstruction from the CPU 160.

The operation portion 182 is an operation portion which receives theoperation input operated by a user and outputs the signal depending onthe received operation input to the CPU 160. For example, in amulti-view image capturing mode for recording the multi-view image, anoperation member such as a shutter button 183 (shown in FIG. 4A or thelike) for instructing an imaging operation start and an imagingoperation end of the captured image for creating the multi-view image isincluded in the imaging device 100. In addition, the multi-view imagecreated in the first embodiment of the invention is a stereoscopic imageof a multi-view (e.g., a stereoscopic image of a panorama shape).Furthermore, the operation portion 182 and the LCD 172 may be integrallyconfigured by the touch panel.

The removable media controller 191 is connected to the removable media192 and performs the reading and writing data to the removable media 192based on the control signal from the CPU 160. For example, the removablemedia controller 191 records various image data such as image datacreated by the imaging portion 110 on the removable media 192 as theimage file (the image content). Furthermore, the removable mediacontroller 191 reads the content such as the image file from theremovable media 192 and outputs the content to the RAM 150 or the likevia the bus 101.

The removable media 192 is a recording device (a recording medium) thatrecords the image data supplied from the removable media controller 191.In the removable media 192, for example, various data such as image dataof a JPEG type are recorded. As the removable media 192, for example, atape (e.g., a magnetic tape) and an optical disc (e.g., a recordable DVD(Digital Versatile Disc) can be used. Furthermore, as the removablemedia 192, for example, a magnetic disk (e.g., a hard disk), asemiconductor memory (e.g., a memory card), and an optical magnetic disc(e.g., MD (MiniDisc)) may be used.

Configuration Example of Image File

FIGS. 2A to 2C are diagrams that schematically show an image file storedin the removable media 192 in the first embodiment of the invention.FIGS. 2A to 2C show an example of a file structure of a still image filein accordance with a MP (Multi Picture) format that records a pluralityof still images as a file (extension: MPO). That is, the MP file (see“CIPA DC-007-2009 multi picture format”) is a file that can record oneor a plurality of images subsequent to a head image.

FIG. 2A shows an example of a file structure of a two view image (a lefteye image and a right eye image for displaying the stereoscopic image),and FIG. 2B shows an example of a file structure of a two view imagewith which a monitor display image (so-called screen nail image) isrelated. Furthermore, FIG. 2C shows an example of a file structure of amulti-view image (a multi-view image of a three view or more).

In the respective file structures shown in FIG. 2A to 2C, a SOI (StartOf Image) is a segment which means the start of the image, and isdisposed at the head of the JPEG image or the monitor display image.Furthermore, an EOI (End OF Image) is a segment which means the end ofthe image, and is disposed at the last of the JPEG image or the monitordisplay image.

Furthermore, an APP (Application Segment) 1, an APP 2 and JPEG imagedata are disposed between the SOI and the EOI. The APP1 and the APP2 areapplication marker segments that house an attachment informationrelative to the JPEG image data. In addition, in front of thecompression image data, marker segments of DQT, DHF, SOF, SOS (Start OfScan) are inserted, but they are omitted. Furthermore, the recordingsequence of DQT (Define Quantization Table), DHF (Define Huffman Table),and SOF (Start Of Frame) is arbitrary. Furthermore, monitor displayimages 304 and 305 shown in FIG. 2B hardly record the APP2 including theMP format attachment information. However, the intent is recorded inwhich the monitor display image is subordinate to the APP2 of the mainimage (an original image). In addition, the monitor display image has anaspect ratio identical to the main image, and, for example, the width is1,920 image pixels and the length can be matched to the aspect ratio ofthis image.

In addition, the APP2 (301 to 303) which is at the top of the filestructure has an important role showing the file structure, andinformation such as the image position (an offset address) of each view,the bite size and whether or not the representative image is recordedtherein.

Herein, the recording of the multi-view image will be simply explainedwith reference to “6.2.2.2 stereoscopic image” and “the selection ofA.2.1.2.3 representative image” of “CIPA DC-007-2009 multi pictureformat”. In “6.2.2.2 stereoscopic image”, the following (1) isdescribed, and in “the selection of A.2.1.2.3 representative image”, thefollowing (2) is described.

(1) In the stereoscopic image, the view number should give the number soas to be an ascension sequence from a left view to a right view towardthe subject.

(2) When the stereoscopic image is recorded, the image used as therepresentative image, it is recommended that, in the case of the viewnumber being an even number, the image used as the representative imageuses the image (image near the center of the whole view) of the viewnumber represented by (view number/2) or (view number/2)+1), and in thecase of the view number being an odd number, the image uses the image ofthe view number represented by (view number/2+0.5).

In the case according to the rule, since it is packed on the upperaddress on the file by the left view image, normally, the sequence ofthe composition processing, encoding or the like is performed in advanceby the left view image. In this case, for example, when therepresentative image which is the center image is review-displayed, itis difficult to perform the review display of the representative image,until the composition processing of the center image is finished. Thus,in the first embodiment of the invention, an example is shown in whichthe representative image is rapidly displayed after the imagingoperation is finished. However, it is possible to appropriately changethe display timing of the representative image depending on thepreference of a user or the like. In addition, the review display is adisplay operation in which, when the recording instruction operation ofthe still image is performed in the state in which the imaging mode ofthe still image is set, after the imaging processing of the capturedimage by the recording instruction operation is finished, for a certainperiod of time, the captured image created by the imaging processing isautomatically displayed.

Selection Example of Recording Target Image

FIGS. 3A and 3B are diagrams that show display examples of settingscreens which set imaging modes of a multi-view image by the imagingdevice 100 in the first embodiment of the invention. The respectivesetting screens, for example, are displayed on the LCD 172 depending onthe user operation from the operation portion 182.

FIG. 3A shows a display example of a setting screen 350 for setting anyone of the two view image capturing mode and the multi-view imagecapturing mode as the capturing mode. In the setting screen 350, a twoview image capturing mode selection button 351, a multi-view imagecapturing mode selection button 352, a determination button 353, and areturn button 354 are provided.

The two view image capturing mode selection button 351 is a button thatis pressed down when the two view image capturing mode is set as thecapturing mode of the multi-view image. The two view image capturingmode is a capturing mode for capturing the two view image. Furthermore,when the two view image capturing mode is set depending on thepress-down operation of the two view image capturing mode selectionbutton 351, the image created by the imaging portion 110 is recorded asthe image file of the two view image shown in FIG. 2A or 2B.

The multi-view image capturing mode selection button 352 is a buttonthat is pressed down when the multi-view image capturing mode is set asthe capturing mode of the multi-view image. The multi-view imagecapturing mode is a capturing mode for capturing multi-view image ofequal to or more than three view images, may set the view numberbecoming the recording target in advance, and can change the view numberbecoming the recording target by the user operation. The change exampleis shown in FIG. 3B. Furthermore, when the multi-view image capturingmode is set depending on the press-down operation of the multi-viewimage capturing mode selection button 352, the image created by theimaging portion 110 is recorded as the image file of the multi-viewimage shown in FIG. 2C.

The determination button 353 is a button that is pressed down after thepress-down operation selecting the two view image capturing mode or themulti-view image capturing mode is performed, when the selection thereofis determined. The return button 354, for example, is a button that ispressed down when returning to the display screen displayed just beforethat.

FIG. 3B is a display example of a setting screen 360 for setting theview number becoming the recording target by the user operation when themulti-view image capturing mode is set. In the setting screen 360 shownin FIG. 3B, a view number axis 361, a minus display area 362, a plusdisplay area 363, a designation position marker 364, a determinationbutton 365, and a return button 366 are provided.

The view number axis 361 is an axis displaying the view number becomingthe designation target by the user operation, and the respectivegradations on the view number axis 361 correspond to the values of theview. For example, the gradation proximate to the minus display area 362among the respective gradations on the view number axis 361 correspondsto the three view image. Furthermore, the gradation proximate to theplus display area 363 among the respective gradations on the view numberaxis 361 corresponds to the maximum view (e.g., 15 view).

The designation position marker 364 is a marker for designating the viewnumber designated by the user operation. For example, by the operationusing a cursor 367 or the touch operation (in the case of including thetouch panel), a user can move the designation position marker 364 to aposition on a desired view number axis 361, thereby designating the viewnumber becoming the recording object.

The determination button 365 is a button which is pressed down, afterthe designation position marker 364 is moved to the position on the viewnumber axis 361 desired by a user, when the designation is determined.The return button 366 is a button which is pressed down, for example,when returning to the display screen displayed immediately before that.

Imaging Operation Example of Multi-view Image and Notification Exampleof the State of Progress

FIGS. 4A and 4B are diagrams that schematically show an imagingoperation when the multi-view image is created using the imaging device100 in the first embodiment of the invention and a notification exampleof the state of progress of the imaging operation.

FIG. 4A schematically shows a case where the imaging operation in thecase of creating the multi-view image using the imaging device 100 isviewed from the upper surface. That is, FIG. 4A shows an example inwhich a user performs the operation (so-called panning (a swingoperation)) of moving the imaging device 100 in a horizontal direction(the direction of arrow 370) based on the imaging position of theimaging device 100, thereby creating the multi-view image. An imageangle (an angle of view of a horizontal direction) of the imaging device100 in this case is cc, and the range (the imaging range) becoming theimaging target by a series of panning operations is schematically shownby thick dotted lines 371.

FIG. 4B shows a display example of a state of progress notificationscreen 380 displayed on the LCD 172 when the multi-view image capturingmode (three view or more) is set. In the state of progress notificationscreen 380, a progress bar 381 for notifying the state of progress ofthe imaging operation of the multi-view image, and operational supportinformation 382 and 383 are provided.

The progress bar 381 is a bar-shaped graph for notifying the state ofprogress of the user operation (the panning operation of the imagingdevice 100) in a case where the multi-view image capturing mode is setto the user. Specifically, the progress bar 381 indicates that thecurrent operation amount (a gray portion 384) relative to the wholeoperation amount (e.g., the rotation angle of the panning operation)necessary in the multi-view image capturing mode progresses by a certainratio. In addition, in regard to the progress bar 381, based on thedetection result of the movement amount between the adjacent capturedimages in the time axis and the movement direction, the CPU 160calculates the current operation amount, thereby changing the displaystate based on the current operation amount. As the movement amount andthe movement direction, for example, motion vector (GMV (Global MotionVector)) corresponding to the movement of all the captured imagegenerated due to the movement of the imaging device 100 is detected. Inaddition, based on the angular velocity detected by the gyro sensor 115,the CPU 160 may calculate the current operation amount. Furthermore, theCPU 160 may calculate the current operation amount using the detectionresults of the movement amount and the movement direction, and theangular velocity detected by the gyro sensor 115. In this manner, a usercan easily understand that a certain panning operation may be performedby displaying the progress bar 381 during imaging of the multi-viewimage.

The operational support information 382 and 383 are information forsupporting the user operation (the panning operation of the imagingdevice 100) in a case where the multi-view image capturing mode is set.As the operational support information 382, for example, a message forsupporting the user operation is displayed. Furthermore, as theoperational support information 383, for example, an arrow (an arrowindicating the operation direction thereof) for supporting the useroperation is displayed.

Imaging Operation Example of Multi-View Image and Recording Example ofCaptured Image Created Thereby

FIGS. 5A and 5B are diagrams that schematically show an imagingoperation at the time of the creation of the multi-view image by theimaging device 100 in the first embodiment of the present invention andan example of a flow of a plurality of captured images created thereby.

FIG. 5A schematically shows a case where the imaging operation is viewedfrom the upper surface when the multi-view image is created using theimaging device 100. In addition, FIG. 5A is identical to the exampleshown in FIG. 4A except that rectangles 372 to 374 are added. That is,in FIG. 5A, the captured images (images (#1) 401, (#i) 404 and (#M) 405)shown in FIG. 5B are imaginarily disposed on the circle (on the dottedlines 371) and the positional relationship when the imaging range isviewed from the upper surface is schematically shown by rectangles 372to 374. In addition, in the rectangles 372 to 374, the correspondingnumbers (#1, #i, and #M) are given. The plurality of captured imagesthus generated is the captured image which is created by performing theimaging operation so that the same subject is included in an area of atleast a part in the horizontal direction.

FIG. 5B schematically shows the state in which the captured images (theimages (#1) 401 to (#M) 405) created by the panning operation shown inFIG. 5A are maintained in the RAM 150. That is, as shown in FIG. 5A,during a panning operation of the imaging device 100 by a user, theimaging portion 110 sequentially creates the images (#1) 401 to (#M)405. Herein, the images (#1) 401 to (#M) 405 are a plurality of capturedimages having offsets in the horizontal direction, and the upper limitnumber thereof can be about 70 to 100. In addition, in regard to theimages (#1) 401 to (#M) 405, the number is given in a time series. Inthis manner, when the recording instruction operation of the multi-viewimage is performed in the imaging device 100, the plurality of capturedimages created during the imaging operation is sequentially recorded inthe RAM 150. In addition, the recording instruction operation of themulti-view image can be performed by maintaining the state of pressingdown the shutter button 183 in a state in which the multi-view imagecapturing mode is set.

Creation Example of Multi-view Image

FIGS. 6A to 8C are diagrams that schematically show creation methodswhen the multi-view image is created by the imaging device 100 in thefirst embodiment of the invention. In the example, an example is shownin which, as the multi-view image, an image constituted from 15 views iscreated.

FIG. 6A schematically shows the image (#i) 404 created by the imagingportion 110 by means of a rectangle. In FIG. 6A, in the image (#i) 404,a take-out area (an image area for each view becoming the compositionsubject) of the image used upon creating the multi-view image is shownby the view numbers (views 1 to 15) the corresponding multi-view image.Herein, the length of the horizontal direction in the image (#i) 404 isW1 and the length of the horizontal direction in the take-out area(short area) used in the composition of the center image (the multi-viewimage of view 8) is w. In this case, the take-out area of the centerarea is determined in the center of the horizontal direction in theimage (#i) 404 (that is, W1=W2×2). Furthermore, the length of thehorizontal direction in the take-out area of each view in the image (#i)404 is identical (that is, w). Herein, the length w of the horizontaldirection in the take-out area of each view greatly depends on themovement amount between the respective images of the image (#1) 401 to(#M) 405 created by the imaging portion 110. Thus, the calculationmethod of the length w of the horizontal direction in the take-out areasof the respective views and the positions of the take-out areas of therespective views in the images (#1) 401 to (#M) 405 will be described indetail with reference to FIGS. 7 to 8C.

FIG. 6B schematically shows a creation method of creating the multi-viewimage using the images (#1) 401 to (#M) 405 maintained in the RAM 150.FIG. 6B shows an example of creating a view j image 411 using the images(#1) 401 to (#M) 405 maintained in the RAM 150. In FIG. 6B, among theimages (#1) 401 to (#M) 405 maintained in the RAM 150, the image areabecoming the composition target of the view j image is shown by gray. Inthis manner, in regard to each of the images (#1) 401 to (#M) 405maintained in the RAM 150, the multi-view image is created using theimage area of at least a part.

Next, a setting method of setting the take-out area in the images (#1)401 to (#M) 405 maintained in the RAM 150 will be described.

FIG. 7 is a diagram that schematically shows the relationship betweenthe imaging element 111, the focus distance and the angle of view in thefirst embodiment of the invention. In addition, the imaging element 111and the optical unit 112 are included in the imaging portion 110.Herein, the width of the imaging element 111 is a width IE1 [mm] of theimaging element. In this case, the width IE1 of the imaging element canbe obtained by the following equation 1.

IE1=p×h  equation 1

In addition, p[um] is a value that indicates a pixel pitch of theimaging element 111, and h [pixel] is a value that indicates thehorizontal pixel number of the imaging element 111.

Furthermore, the angle of the imaging device 100 in the example shown inFIG. 7 is a [deg]. In this case, the angle α can be obtained thefollowing equation 2.

α=(180/π)×2×tan⁻³)/(2×f)  equation 2

In addition, f [mm] is a value that shows a focus distance in theimaging device 100. By using the angle α thus calculated, an angle ofview (a pixel density) μ [deg/pixel] near one pixel constituting theimaging element 111 can be obtained the following equation 3.

μ=α/h  equation 3

Herein, when the multi-view image capturing mode is set in the imagingdevice 100, the continuous speed (that is, a frame number per onesecond) of the image in the multi-view image capturing mode is s [fps].In this case, a length (a width of a take-out area) w [pixel] of atake-out area of one view (a maximum take-out area) on one captured areacan be obtained the following equation 4 of the horizontal direction.

w=(d/s)×(1×μ)  equation 4

In addition, d [deg/sec] is a value that shows a vibration angularvelocity of a user who operates the imaging device 100. In this manner,by using the vibration angular velocity d of a user who operates theimaging device 100, the width (the width of the maximum take-out area) wof the take-out area can be obtained.

FIGS. 8A to 8C show calculation methods of a shifting amount of thetake-out area becoming the composition target of the multi-view image inthe captured image (image (#i) 404) maintained in the RAM 150. FIG. 8Ashows the take-out area of the center image (the multi-view image ofview 8). FIG. 8B shows the take-out area of the leftmost view image (themulti-view image of the view 1). FIG. 8C shows the take-out areas of therightmost view image (the multi-view image of the view 15).

As mentioned above, when the composition processing of the multi-viewimage is performed, the image (the elongated image) becoming thecomposition target of the multi-view image is taken out from each of therespective captured images (#1) 401 to (#M) 405 that are created by theimaging portion 110 and are maintained in the RAM 150. That is, theimage (the elongated image) becoming the composition target is taken outwhile shifting the position of the take-out area (the elongated area) inone captured image maintained in the RAM 150. In this case, based on theinter-relationship between the respective images, each image isoverlapped with the taken-out image and is composed. Specifically, themovement amount and the movement direction (i.e., a relativedisplacement between the adjacent captured images) between two adjacentcaptured images in the time axis are detected. Moreover, based on thedetected movement amount and the movement direction (the movement amountand the movement direction between the adjacent images), each of thetaken-out images are composed so that overlap areas are overlapped witheach other, whereby the multi-view image is created.

Herein, a calculation method of the size and the position of thetake-out area (the elongated area) in one captured image maintained inthe RAM 150 and a shifting amount of a view j will be described.

After the imaging processing by the imaging portion 110 and therecording processing to the RAM 150 are finished, it is calculated whicharea is the take-out area in each of the plurality of captured imagesmaintained in the RAM 150. Specifically, as shown in equation 4, thewidth of the take-out area is calculated, and the position of thehorizontal direction in the take-out area used in the composition of thecenter image (the multi-view image of the view 8) is a position of thecenter of each captured image maintained in the RAM 150.

Herein, the position of the horizontal direction in the take-out areaused in the composition of another multi-view image other than thecenter image (the multi-view image of the view 8) is calculated on thebasis of the position of the horizontal direction in the take-out areaused in the composition of the center image (the multi-view image of theview 8). Specifically, the position shifted from the initial position(the middle position) is calculated depending on a difference in viewnumber between the center view (view 8) and the view j. That is, theshifting amount MQj of the view j can be obtained by the followingequation 5.

MQj=(CV−OVj)×β  equation 5

In addition, the CV is a value that shows the center view among themulti-view image, and the OVj is a value that shows another view (viewj) other than the center view among the multi-view image. Furthermore, βis a value that shows a shifting amount (an elongated position shiftingamount) of the position of the take-out area per one view. In addition,the size (the elongated size) of the take-out area does not change.

Herein, the calculation method of the elongated position shifting amountβ will be described. The elongated position shifting amount β can beobtained by the following equation 6.

β=(W1−w×2)/VN  equation 6

In addition, W1 is a value that shows the horizontal size per onecaptured image maintained in the RAM 150, w is a value that shows thewidth (the width of the maximum take-out area) of the take-out area, andVN is a value that shows the view number of the multi-view image. Thatis, a value, in which W3 (=W1−w×2) shown in FIG. 8A is divided by theview number (15), is calculated as the elongated position shiftingamount 13.

In this manner, the elongated position shifting amount β is calculatedso that the image (the elongated image) taken out at the time of thecomposition processing of the leftmost view image or the rightmost viewimage is disposed at least in a left and a right end among the capturedimage maintained in the RAM 150.

In addition, in the case of performing the composition processing of theplane image (a two-dimensional image) of a panorama shape, the middleelongated image (the image corresponding to the view 8) corresponding tothe width (the width of the maximum take-out area) w of the take-outarea is sequentially taken out and composed. Furthermore, in the case ofperforming the composition processing of the two view image, twotake-out areas are set so that a shifting amount (the offset amount) OFfrom the middle elongated image is identical to the left view and theright view. In this case, the offset amount (the minimum elongatedoffset amount) OF. [pixel] which is allowable in the vibration angularvelocity d of a user who operates the imaging device 100 can be obtainedby the following equation 7

OF _(min) =w/2  equation 7

In addition, the minimum elongation offset amount OF_(min) is a minimumpermitted elongated offset amount in which an overlap of the left eyeelongated image and the right eye elongated image is not generated (notoverlapped).

Furthermore, the maximum permitted elongated offset amount (the maximumelongated offset amount) OF_(max) for setting so that the take-out areaused in the composition processing of the two view image does not comeout to the outside of the imaging area of the captured image maintainedin the RAM 150 can be obtained by the following equation 8.

OF _(max)=(t−OF _(min))/2  equation 8

Herein, t [pixel] is a horizontal effective size of one image created bythe imaging portion 110. The horizontal effective size t corresponds tothe horizontal pixel number which is the transverse width of thecaptured image maintained in the RAM 150.

Recording Processing Example of Multi-view Image

FIG. 9 is a diagram that schematically shows a flow until the multi-viewimage created by the imaging device 100 in the first embodiment of theinvention is recorded on a removable media 192. FIG. 9 shows an exampleof a flow of the data on the RAM 150 when the view j image 411 createdusing the images (#1) 401 to (#M) 405 maintained in the RAM 150 isrecorded as the MP file 430 (extension: .MPO). In addition, the images(#1) 401 to (#M) 405 shown in FIG. 9 is the same as FIG. 6A.

As mentioned above, the images (#1) 401 to (#M) 405 created by theimaging portion 110 are sequentially recorded on the RAM 150. Next, inregard to each of the images (#1) 401 to (#M) 405 maintained in the RAM150, the CPU 160 calculates the take-out area of the view j, therebyacquiring the image included in the take-out area. Next, using the imageacquired from the respective take-out areas of the images (#1) 401 to(#M) 405, the CPU 160 creates the composite image (the view j image 411)of the view j. In addition, in the present example, there is shown anexample in which the CPU 160 creates the composite image of themulti-view image, but a hardware or a software (an accelerator) for theimage composition may be separately provided, thereby creating thecomposite image of the multi-view image.

Next, the resolution conversion portion 120 performs the resolutionconversion in the view j image 411 and set the same as the final image(the view j image 420) of the view j. Next, the image compressionexpansion portion 130 compresses the view j image 420 to the image dataof the JPEG type. Next, the CPU 160 performs the packing processing (apacking processing such as a header addition) of the view j image 420which is compressed to the JPEG type to the MP file 430. Furthermore,the same is also true for the creation of other multi-view images.Moreover, when the composition processing of the whole multi-view imageis finished, the removable media controller 191 records the MP file 430on the removable media 192 based on the control of the CPU 160.

In addition, FIG. 9 schematically shows the state in which the recordingof the multi-view image of the view j among the MP file 430 is finished.That is, in the MP file 430, an area of the multi-view image where therecording is finished is shown by a solid line, and an area of themulti-view image where the recording is not finished is shown by adotted line.

Display Processing Example of Representative Image of Multi-view Image

FIG. 10 is a diagram that schematically shows a flow until therepresentative image of the multi-view image created by the imagingdevice 100 in the first embodiment of the invention is displayed. FIG.10 shows an example of a flow of the data on the RAM 150 when the view 8image created using the images (#1) 401 to (#M) 405 maintained in theRAM 150 is recorded on the LCD 172 as the representative image. Inaddition, the images (#1) 401 to (#M) 405 shown in FIG. 10 is the sameas FIG. 6A.

In addition, since the creation of the composite image (therepresentative image 441) of the view 8 and the final image (therepresentative image 442) of the view 8 are identical to the exampleshown in FIG. 9, the description thereof will be omitted.

After the representative image 442 is created, the resolution conversionportion 120 performs the resolution conversion in regard to therepresentative image 442 so as to be the image size optimum in thedisplay and sets the same as the display image (the representative image443) of the view 8. Next, the LCD controller 171 displays therepresentative image 443 on the LDC 172 based on the control of the CPU160. That is, the representative image 443 is review-displayed, evenafter the review display is performed in this manner, the createdrepresentative image 443 is maintained in the RAM 150 until beingsubjected to the packing processing to the MP file 430 shown in FIG. 9.As a result, it is possible to reduce the overhead at the time of thecomposition processing without performing the composition processing ofthe representative image 442 again.

In this manner, the multi-view image is created using the plurality ofimages created by the imaging portion 110. Furthermore, therepresentative image of the created multi-view image is initiallydisplayed on the LCD 172.

Functional Configuration Example of Imaging Device

FIG. 11 is a block diagram that shows a functional configuration of theimaging device 100 in the first embodiment of the invention. The imagingdevice 100 includes an operation reception portion 210, a posturedetection portion 220, a control portion 230, an imaging portion 240, acaptured image maintenance portion 250, a movement amount detectionportion 260, a composition portion 270, a display control portion 280, adisplay portion 285, a recording control portion 290, and a contentmemory unit 300.

The operation reception portion 210 is an operation reception portionwhich receives the operation content operated by a user, and suppliesthe operation signal depending on the received operation content to thecontrol portion 230. For example, the operation reception portion 210corresponds to the input control portion 181 and the operation portion182 shown in FIG. 1.

The posture detection portion 220 detects a change in posture of theimaging device 100 by detecting the acceleration, the movement, the tiltor the like of the imaging device 100, and outputs the posture changeinformation relating to the change of the detected posture to thecontrol portion 230. In addition, the posture detection portion 220corresponds to the gyro sensor 115 shown in FIG. 1. Furthermore, theposture detection portion 220 is an example of the detection portiondescribed in the claims.

The control portion 230 controls the respective portions of the imagingdevice 100 based on the operation content from the operation receptionportion 210. For example, when the setting operation of the capturingmode is received by the operation reception portion 210, the controlportion 230 sets the capturing mode depending on the setting operationthereof. Furthermore, for example, the control portion 230 interprets achange amount (the movement direction, the movement amount or the like)of the posture of the imaging device 100 based on the posture changeinformation, which is output from the posture detection portion 220, andoutputs the interpretation result to the composition portion 270 and thedisplay control portion 280. Furthermore, for example, the controlportion 230 performs a control in which, after the creation processingof the plurality of captured images by the imaging portion 240 isfinished, the multi-view image becoming a predetermined sequence (e.g.,the middle view) among the plurality of multi-view images becoming thecreation target by the composition portion 270 is displayed on thedisplay portion 285 as the representative image. In this manner, afterdisplaying the representative image, the control portion 230 performs acontrol in which, for example, at least a part of the created multi-viewimage is sequentially displayed on the display device 285 according to apredetermined rule (e.g., each of the views). Furthermore, for example,after the creation processing of the plurality of captured images by theimaging portion 240 is finished, the control portion 230 performs acontrol in which information (e.g., the progress bar 521 shown in FIGS.19 and 21) relating to the progress of the creation of the multi-viewimage by the composition portion 270 is displayed on the display portion285. In this case, immediately after the creation processing of theplurality of captured images by the imaging portion 240 is finished, thecontrol portion 230 performs a control in which the progress informationis displayed on the display portion 285. In addition, the controlportion 230 corresponds to the CPU 160 shown in FIG. 1.

The imaging portion 240 images the subject to create the captured imagebased on the control of the control portion 230, and supplies thecreated captured imaged to the captured image maintenance portion 250.Furthermore, when the two view image capturing mode or the multi-viewimage capturing mode is set, the imaging portion 240 images the subjectto create a plurality of captured images that continues in a time seriesand supplies the created captured image to the captured imagemaintenance portion 250. In addition, the imaging portion 240corresponds to the imaging portion 110 shown in FIG. 1.

The captured image maintenance portion 250 is an image memory, whichmaintains the captured image created by the imaging portion 240, andsupplies the maintained captured image to the composition portion 270.In addition, the captured image maintenance portion 250 corresponds tothe RAM 150 shown in FIG. 1.

The movement amount detection portion 260 detects the movement amountand the movement direction between the adjacent captured images in thetime axis in regard to the captured image maintained in the capturedimage maintenance portion 250, and outputs the detected movement amountand movement direction to the composition portion 270. For example, themovement amount detection portion 260 performs a matching processing(that is, a matching processing of distinguishing the imaging area ofthe same subject) between the pixels constituting the adjacent twocaptured images, and calculates the pixel number moved between therespective captured images. In the matching processing, basically, aprocessing is performed in which the subject is supposed to be stopped.In addition, when a moving body is included in the subject, a motionvector different from a motion vector of the whole captured image isdetected, but the motion vector corresponding to the moving body is outof the detection target, whereby the processing is performed. That is,only the motion vector (GMV: global motion vector) corresponding to themotion of the whole captured image generated due to the movement of theimaging device 100 is detected. In addition, the movement amountdetection portion 260 corresponds to the CPU 160 shown in FIG. 1.

The composition portion 270 creates the multi-view image using theplurality of captured images maintained in the captured imagemaintenance portion 250 based on the control of the control portion 230,and supplies the created multi-view image to the display control portion280 and the recording control portion 290. That is, the compositionportion 270 calculates the take-out area in each of the plurality ofcaptured images maintained in the captured image maintenance portion 250based on the interpretation result (the interpretation result of thechange amount of the posture of the imaging device 100) output from thecontrol portion 230. Moreover, the composition portion 270 takes theimage (the elongated image) out of the take-out area in each of theplurality of captured images and composes the taken-out image to createthe multi-view image. In this case, the composition portion 270 composesthe taken-out image in an overlapped manner to create the multi-viewimage based on the movement amount and the movement direction outputfrom the movement amount detection portion 260. The multi-view imagesthus created are the plurality composite images having the sequencerelationship (the respective views) based on a predetermined rule.Furthermore, for example, the composition portion 270 initially createsthe representative image immediately after the creation processing ofthe plurality of captured images by the imaging portion 240. Inaddition, the initially created image may be changed by a user operationor the setting content is finished. In addition, the composition portion270 corresponds to the resolution conversion portion 120, the RAM 150and the CPU 160 shown in FIG. 1.

The display control portion 280 displays the multi-view image created bythe composition portion 270 on the display portion 285 based on thecontrol of the control portion 230. For example, the display controlportion 280 displays the multi-view image becoming the predeterminedsequence (e.g., the middle view) among the plurality of multi-viewimages becoming the creation target by the composition portion 270 onthe display portion 285 as the representative image, after the creationprocessing of the plurality of captured images by the imaging portion240 is finished. As a result, after displaying the representative image,the display control portion 280, for example, sequentially displays atleast a part of the created multi-view image on the display portion 285according to the predetermined rule (e.g., the respective views). Inaddition, for example, the display control portion 280 displays theinformation (e.g., the progress bar 521 shown in FIGS. 19 to 21)relating to the progress of the creation of the multi-view image by thecomposition portion 270 on the display portion 285, after the creationprocessing of the plurality of captured images by the imaging portion240 is finished. The display examples will be explained in detail withreference to FIGS. 12A to 21D. In addition, the display control portion280 corresponds to the resolution conversion portion 120 and the LCDcontroller 171 shown in FIG. 1.

The display portion 285 is a display portion that displays the imagesupplied from the display control portion 280. Furthermore, various menuscreens or various images are displayed on the display portion 285. Inaddition, the display portion 285 corresponds to the LCD 172 shown inFIG. 1.

The recording control portion 290 performs a control which records themulti-view image created by the composition portion 270 on the contentmemory unit 300 based on the control of the control portion 230. Thatis, the recording control portion 290 relates the representative imageinformation showing the representative image of the multi-view image andthe sequence relationship (e.g., the view number) of the multi-viewimage to the created multi-view image, thereby recording the multi-viewimage on the recording medium as the MP file. In addition, the recordingcontrol portion 290 corresponds to the image compression expansionportion 130 and the removable media controller 191 shown in FIG. 1.

The content memory unit 300 stores the multi-view image created by thecomposition portion 270 as the image file (the image content). Inaddition, the content memory portion 300 corresponds to the removablemedia 192 shown in FIG. 1.

Display Example of Representative Image

FIGS. 12A to 12C are diagrams that show display examples of therepresentative image displayed on the display portion 285 in the firstembodiment of the invention. FIGS. 12A to 12C show examples in which themulti-view images of seven views are created and the respective imagesare related to each other and are stored in the content memory unit 300.Furthermore, in FIGS. 12A to 12C, in regard to the multi-view images ofthe seven views, from the left view (view 1) to the right view (view 7)toward the subject, the view numbers are given so as to be an ascendingsequence and the view numbers are shown in the rectangle indicating theimage. Furthermore, in FIGS. 12A to 12C, an example is shown in whichthe middle image (the multi-view images of the view 4) is therepresentative image among the multi-view images of the seven views. Inaddition, as the representative image, for example, the image adjoiningor approaching the middle image may be used,

FIG. 12A shows an example of the multi-view image becoming the recordingtarget to the content memory unit 300. In addition, in FIG. 12A, each ofthe images are shown in parallel in the sequence of the view number.

FIG. 12B shows the multi-view images of the views 1 to 7 created by thecomposition processing in a line in the creation sequence thereof afterthe imaging operation for creating the multi-view images of the views 1to 7 shown in FIG. 12A is finished. That is, the representative image(the multi-view image of the view 4) initially displayed on the displayportion 285 becomes the target of the initial composition processing.After the composition processing of the representative image (themulti-view image of the view 4) is finished, the composition processingof other multi-view images is performed. For example, the compositionprocessing is performed in the sequence (the sequence of the views 1 to3 and 5 to 7) of view numbers.

FIG. 12C shows an example in which the representative image is displayedas the image initially displayed on the display portion 285 duringcomposition processing shown in FIG. 12B. In this manner, by initiallydisplaying the representative image, it is possible to rapidly andeasily confirm the representative image of the multi-view image.

As mentioned above, a case has been shown in which, in the case ofrecording the multi-view images of three views or more, only therepresentative image is review-displayed. However, other multi-viewimages other than the representative image may be displayed depending onthe preference of a user. Thus, hereinafter, an example will be shownwhich sequentially review-displays other multi-view images other thanthe representative image.

FIGS. 13A to 16C show diagrams that show display transition examples ofthe multi-view images displayed on the display portion 285 in the firstembodiment of the invention. In FIGS. 13A to 16C, examples are shown inwhich, similarly to FIGS. 12A to 12C, when the multi-view images of theseven views are related to each other and are recorded in the contentmemory unit 300, the middle image (the multi-view image of the view 4)is set as the representative image. Furthermore, in FIG. 13A to 16C,similarly to FIGS. 12A and 12C, in regard to the multi-view images ofthe seven views, from the left view (view 1) to the right view (view 7)toward the subject, the view numbers are given so as to be an ascendingsequence and the view numbers are shown in the rectangle indicating theimage.

FIGS. 13A, 14A, 15A, and 16A show an example of the multi-view imagebecoming the recording target to the content memory unit 300. Inaddition, FIGS. 13A, 14A, 15A, and 16A are the same as the example shownin FIG. 12A.

FIGS. 13B and 14B shows the multi-view images of the view 1 to view 7created by the composition processing in a creation sequence in a lineafter the imaging operation for creating the multi-view images of theview 1 to view 7 shown in FIG. 12A is finished. FIGS. 13B and 14B areidentical to the example shown in FIG. 12B.

FIG. 13C shows the display transition example of the multi-view imagedisplayed on the display portion 285 during composition processing shownin FIG. 13B. That is, FIG. 13C shows an example in which, after theimaging operation for creating the multi-view image is finished, themulti-view image created by the composition processing is sequentiallyreview-displayed depending on the creation sequence.

FIG. 14C shows the display transition example of the multi-view imagedisplayed on the display portion 285 during composition processing shownin FIG. 14B. That is, FIG. 14C shows an example in which, after theimaging operation for creating the multi-view image is finished, themulti-view image created by the composition processing is sequentiallyreview-displayed in a descending sequence of the view number from therepresentative image, and, after the display, the multi-view image isreview-displayed in an ascending sequence of the view number.

In this manner, it is possible to initially review-display therepresentative image, and when the display of the representative image,sequentially review-display the multi-view image created by thecomposition processing according to a predetermined rule. As a result,initially, the representative image of the multi-view image can berapidly confirmed, and after confirmation, another multi-view image canbe easily confirmed.

Herein, when reproducing the multi-view image, the representative imageof the multi-view image is displayed in a list on the selection screenfor selecting a desired multi-view image in many cases. Thus,immediately after the imaging processing by the imaging portion 240 isfinished, the representative image is review-displayed. For that reason,it is possible to easily confirm the same image as the representativeimage, which is displayed in a list at the time of the reproduction, atthe time of the review-display. As a result, it is possible to reducedisharmony at the time of the reproduction.

Furthermore, immediately after the imaging processing by the imagingportion 240 is finished, by initially synthesizing and review-displayingthe representative image of the multi-view image, a user does not haveto have the time until the representative image is composed from theleft view image. For that reason, a user can make the timing ofconfirming the multi-view image becoming the recording target faster. Asa result, for example, after confirmation of the multi-view imagebecoming the recording target, it is possible to solve the disadvantagethat the cancel timing of the imaging is delayed. In addition, thedisplay sequence of the multi-view image may be changed depending on thepreference of a user. Next, the display transition example thereof willbe shown.

FIGS. 15B and 16B show the multi-view images of the view 1 to view 7created by the composition processing in a creation sequence in a lineafter the imaging operation for creating the multi-view images of theview 1 to view 7 shown in FIG. 12A is finished. In the example, thecomposition processing of the multi-view image is performed so as to bethe ascending sequence from the left view (view 1) to the right view(view 7) toward the subject.

FIG. 15C shows the display transition example of the multi-view imagedisplayed on the display portion 285 during composition processing shownin FIG. 15B. That is, FIG. 15C shows an example in which, after theimaging operation for creating the multi-view image is finished, themulti-view image created by the composition processing is sequentiallyreview-displayed depending on the creation sequence.

FIG. 16C shows the display transition example of the multi-view imagedisplayed on the display portion 285 during composition processing shownin FIG. 16B. That is, similarly to the example shown in FIG. 15C, FIG.16C shows an example in which, after the multi-view image isreview-displayed in the ascending sequence of the view number, themulti-view image is further sequentially review-displayed in adescending sequence of the view number. That is, in the example shown inFIG. 16C, during the time until the recording processing to the contentmemory unit 300 of the created multi-view image is finished, a displayoperation of sequentially review-displaying the multi-view image in theascending sequence of the view number is repeatedly performed. Inaddition, in the examples shown in FIGS. 15A to 16C, the examples havebeen shown in which the multi-view image is sequentiallyreview-displayed in the ascending sequence of the view number, but themulti-view image may be review-displayed in the descending sequence ofthe view number.

In this manner, the composition processing of the multi-view image isperformed so as to be the ascending sequence of the view number, and themulti-view image created by the composition processing can besequentially review-displayed. As a result, it is possible to easilyconfirm the representative image of the multi-view image and othermulti-view images in the ascending sequence or the descending sequenceof the view number of the multi-view image. In this manner, byperforming the review-display in the ascending sequence or thedescending sequence of the view number, it is possible to easily performconfirmation of the multi-view image depending on the reproductionsequence of the multi-view image.

In addition, FIGS. 15A to 16C show examples in which the review-displayis performed in the ascending sequence or the descending sequence of theview number, but at a point of time when the composition processing ofthe multi-view image is finished, it is desirable to review-display therepresentative image. That is, it is desirable to set the image, whichis review-displayed at last, as the representative image.

State of Progress Notification Example of Composition Processing ofMulti-View Image

FIGS. 17A to 17C are diagrams that schematically show a state ofprogress notification information of a composition processing of themulti-view image displayed on the display portion 285 in the firstembodiment of the invention. FIGS. 17A to 17C show examples in which, asthe state of progress notification information (progress information) ofthe composition processing of the multi-view image, progress bars aredisplayed. The progress bars display how the composition processing ofthe multi-view image is progressing through a certain degree of ratiousing rod shaped graphs. Furthermore, the examples shown in FIGS. 17A to17C show examples in which the seven view images are created as themulti-view image.

FIG. 17A schematically shows the display method when displaying theprogress bar 500. For example, while the composition processing of themulti-view image is performed, a state of progress notification screen(e.g., a state of progress notification screen 520 shown in FIGS. 19A to19D) provided with the progress bar 500 is displayed on the displayportion 285. The progress bar 500 has a length of L1 in a horizontaldirection.

Herein, in the case of creating the seven view images as the multi-viewimage, the display control portion 280 calculates a value, in which thelength of the horizontal direction in the progress bar 500 is divided by7, and sets seven rectangular areas in the progress bar 500 by thecalculated value. That is, as the value in which the length of thehorizontal direction in the progress bar 500 is divided by 7, a lengthL11 (=L12 to L17) is calculated, and seven rectangular areascorresponding to the lengths L11 to L17 is set. The rectangular area isan area which becomes a unit for sequentially changing the display statewhen the composition processing of one multi-view image is finished.

FIG. 17B shows a transition of the composition processing of themulti-view image. FIG. 17B schematically shows the multi-view image, inwhich the composition processing is finished, in a line along the timeaxis. Furthermore, FIG. 17C shows the display transition of the progressbar 500 which is changed depending on the composition processing shownin FIG. 17B. Furthermore, in the examples shown in FIGS. 17B and 17C, inregard to the transition of the composition processing of the multi-viewimage shown in FIG. 17B and the display transition of the progress bar500 which is changed depending on the composition processing shown inFIG. 17C, the composition processing shown in FIG. 17C, thecorresponding relationship is shown in a series left to right.

For example, immediately after the imaging operation of the multi-viewimage is finished, the state of progress notification screen (e.g., thestate of progress notification screen 520 shown in FIGS. 19A to 19D) isdisplayed on the display portion 285. Immediately after the state ofprogress notification screen is displayed, the progress bar 500 isdisplayed as a single color (e.g., white). Next, when the compositionprocessing of the multi-view image is started and the compositionprocessing of one multi-view image is finished, as shown in FIG. 17C,the display control portion 280 changes the display state of therectangular area (a rectangular area corresponding to the length L11) ofthe left end (e.g., changes to gray color).

Furthermore, as shown in FIG. 17C, whenever the composition processingof the multi-view image is finished, the display control portion 280sequentially changes the display state of the rectangular area (therectangular area corresponding to the length L12 to L16) from the leftend by the number the multi-view image in which the compositionprocessing is finished. Moreover, when the composition processing of thewhole multi-view image is finished, the display state of the respectiverectangular areas (that is, all of the progress bars 500) is changed.

In this manner, whenever the composition processing of the multi-viewimage is finished, by changing the display state of the progress bar 500to notify the state of progress of the composition processing of themulti-view image, a user can easily understand the situation of thecomposition processing thereof.

In addition, an example has been shown in which, whenever thecomposition processing of the multi-view image is finished, the displaystate of the progress bar 500 is changed. However, for example, when thenumber of the multi-view image becoming the composition target is large,the plurality of multi-view images is set as one unit, and whenever thecomposition processing of the respective multi-view images is finished,the display state of the progress bar 500 may be changed. For example,when five multi-view images are set as one unit, whenever thecomposition processing of the fifth multi-view image is finished, thedisplay state of the progress bar 500 is changed. As a result, it ispossible to frequently not renew the display state of the progress bar500, and a user can easily view.

Display Example of the State of Progress Notification Screen ofComposition Processing of Two View Image

FIGS. 18A and 18B are diagrams that show display transition examples ofthe state of progress notification screen displayed on the displayportion 285 in the first embodiment of the invention. FIGS. 18A and 18Bshow an example of the state of progress notification screen in the caseof recording of two view image as the multi-view image.

FIG. 18A shows the state of progress notification screen 510 which isdisplayed on the display portion 285 immediately after the imagingoperation of two view image is finished. The representative image (e.g.,the left view image) 513 among two view image is displayed on the stateof progress notification screen 510, and an under-processing message 511is displayed to be overlapped with the representative image 513. Inaddition, the representative image 513 shown in FIGS. 18A and 18B issimply shown by giving a character of the representative image (the leftview image) in the corresponding rectangle. Furthermore, similarly, thedisplay images shown in FIGS. 19A to 21D are simply shown by givingcharacters indicating the respective images image in the correspondingrectangle.

The under-processing message 511 is a character that shows thecomposition processing of two view image is implementing. In addition,on the state of progress notification screen 510, during the time untilthe composition processing of the representative image among two viewimage is finished, only the under-processing message 511 is displayed.

FIG. 18B shows the state of progress notification screen 510 displayedon the display portion 285 immediately after the recording processing oftwo view image is finished. On the state of progress notification screen510, the representative image (e.g., the left view image) 513 among twoview image is displayed, and the processing finish message 512 isdisplayed so as to be overlapped with the representative image 513. Theprocessing finish message 512 is a character showing that the recordingprocessing of two view image is finished.

In this manner, when the recording processing of two view image isperformed, since the number of the image becoming the composition targetis small, it is supposed that the composition processing is relativelydelayed and finished. For that reason, it is possible to display theprogress bar notifying the state of progress on the state of progressnotification screen which is displayed when the recording processing oftwo view image is performed. In addition, the progress bar may bedisplayed depending on the preference of a user.

Display Example of the State of Progress Notification Screen ofComposition Processing of Multi-View Image (Three View or More)

FIGS. 19A to 19D are diagrams that show display transition examples ofthe state of progress notification screen which are displayed on thedisplay portion 285 in the first embodiment of the invention. FIGS. 19Ato 19D show an example of the state of progress notification screen inthe case of recording of three or more multi-view image.

FIG. 19A shows the state of progress notification screen 520 which isdisplayed on the display portion 285 immediately after the imagingoperation of the multi-view image is finished. The representative image524 among the multi-view image is displayed on the state of progressnotification screen 520, and the progress bar 521 and anunder-processing message 522 are displayed so as to be overlapped withthe representative image 524. In addition, the progress bar 521 is thesame as the progress bar 500 shown in FIGS. 17A to 17C. Furthermore, theunder-processing message 522 is a character that shows the compositionprocessing of the multi-view image is implementing. In addition, on thestate of progress notification screen 520, during the time until thecomposition processing of the representative image among the multi-viewimage is finished, only the progress bar 521 and the under-processingmessage 522 are displayed.

FIGS. 19B and 19C show a state of progress notification screen 520displayed on the display portion 285 while the composition processing ofthe multi-view image is performed. On the state of progress notificationscreen 520, similarly to FIG. 19A, the representative image 524, theprogress bar 521 and the under-processing message 522 are displayed.Herein, as shown in FIG. 17C, the display state of the progress bar 521is changed depending on the number of the multi-view image in which theprocessing is finished. In addition, FIG. 19C shows the state ofprogress notification screen 520 displayed on the display portion 285immediately after the composition processing of the whole multi-viewimage is finished.

FIG. 19D shows the state of progress notification screen 520 displayedon the display portion 285 immediately after the recording processing ofthe multi-view image is finished. On the state of progress notificationscreen 520, the representative image 524 among the multi-view image isdisplayed, and the processing finish message 523 is displayed so as tobe overlapped with the representative image 524. The processing finishmessage 523 is a character showing that the recording processing of themulti-view image is finished.

As mentioned above, an example has been shown in which, while thecomposition processing of the multi-view image is performed, therepresentative image of the multi-view image and the progress bar aredisplayed. However, as shown in FIGS. 13A to 16C, while the compositionprocessing of the multi-view image is performed, other images other thanthe representative image among the multi-view image may be sequentiallydisplayed. Furthermore, by other display states other than the progressbar, the state of progress notification information of the compositionprocessing of the multi-view image may be performed. Hereinafter, thedisplay examples will be shown.

FIGS. 20A to 20D are diagrams that show display transition examples ofthe state of progress notification screen which are displayed on thedisplay portion 285 in the first embodiment of the invention. FIGS. 20Ato 20D show an example of the state of progress notification screen inthe case of recording of three or more multi-view image. Furthermore,the examples shown in FIGS. 20A to 20D are modified examples of FIGS.19A to 19D, and the portions common to FIGS. 19A to 19D will be denotedby the identical reference numerals and a part of the descriptionthereof will be omitted.

FIG. 20A shows the state of progress notification screen 530 which isdisplayed on the display portion 285 immediately after the imagingoperation of the multi-view image is finished. Similarly to FIG. 20A,the representative image 531, the progress bar 521 and anunder-processing message 522 are displayed on the state of progressnotification screen 530.

FIGS. 20B and 20C show a state of progress notification screen 530displayed on the display portion 285 while the composition processing ofthe multi-view image is performed. On the state of progress notificationscreen 530, similarly to FIGS. 19B and 19C, the progress bar 521 and theunder-processing message 522 are displayed. However, it is differentfrom FIGS. 19B and 19C in that the multi-view images 532 and 533, inwhich the composition processing is completed, are displayed in thebackground thereof. In addition, the multi-view images 532 and 533, inwhich the composition processing is completed, are the multi-view imageother than the representative image among the multi-view image, and canbe displayed by the sequence shown in FIGS. 13A to 13C or 14A to 14C.

FIG. 20D shows the state of progress notification screen 530 displayedon the display portion 285 immediately after the recording processing ofthe multi-view image is finished. On the state of progress notificationscreen 520, similarly to FIG. 19D, the representative image 531 and theprocessing finish message 523 are displayed. In this manner, it isdesirable to display the representative image immediately after therecording processing of the multi-view image is finished.

FIGS. 21A to 21D are diagrams that show display transition examples ofthe state of progress notification screen which are displayed on thedisplay portion 285 in the first embodiment of the invention. FIGS. 21Ato 21D show an example of the state of progress notification screen inthe case of recording of three or more multi-view image. Furthermore,the examples shown in FIGS. 21A to 21D are modified examples of FIGS.19A to 19D, and the portions common to FIGS. 19A to 19D will be denotedby the identical reference numerals and a part of the descriptionthereof will be omitted.

FIG. 21A shows the state of progress notification screen 540 which isdisplayed on the display portion 285 immediately after the imagingoperation of the multi-view image is finished. Similarly to FIG. 19A,the representative image 524, the progress bar 521 and anunder-processing message 522 are displayed on the state of progressnotification screen 540. However, it is different from FIG. 19A in thatother state of progress notification information (the state of progressnotification information 541) is displayed so as to be overlapped withthe representative image 524. The state of progress notificationinformation 541 is information that notifies the state of progress ofthe composition processing of the state of progress notification screen,and displays that the composition processing of the multi-view imageprogresses by a certain degree of ratio by a numerical value. Theexamples shown in FIGS. 21A to 21D show the state of progressnotification information 541 which notifies the state of progress, by afraction in which the whole number of the multi-view image becoming thetarget of the composition processing is the denominator and the numberof the multi-view image, in which the composition processing iscompleted, is the numerator.

Since the state of progress notification screen 540 shown in FIG. 21A isdisplayed immediately the imaging operation of the multi-view image isfinished, none of the composition processing of the multi-view image isfinished. For that reason, as the state of progress notificationinformation 541, “progress degree (0/7)” is displayed.

FIGS. 21B and 21C show a state of progress notification information 540displayed on the display portion 285 while the composition processing ofthe multi-view image is performed. On the state of progress notificationscreen 540, similarly to FIGS. 19B and 19C, the progress bar 521 and theunder-processing message 522 are displayed. However, it is differentfrom FIGS. 19B and 19C in that the state of progress notificationinformation 541 is displayed. In addition, the progress bar 521displayed while the composition processing of the multi-view image isperformed, and the state of progress notification information 541correspond to each other.

FIG. 21D shows the state of progress notification screen 540 which isdisplayed on the display portion 285 immediately after the recordingprocessing of the multi-view image is finished. On the state of progressnotification screen 520, similarly to FIG. 19D, the representative image531 and the processing finish message 523 are displayed.

In this manner, while the composition processing of the multi-view imageis performed, by displaying the progress bar 521 and the state ofprogress notification information 541, the state of progress thereof canbe further easily understood. In addition, in the embodiment, an examplehas been shown in which the progress bar 521 and the state of progressnotification information 541 are concurrently displayed, but only thestate of progress notification information 541 may be displayed.Furthermore, other state of progress notification information (the stateof progress notification information of the composition processing ofthe multi-view image) indicating that the composition processing of themulti-view image progresses by a certain ratio may be displayed. Asother state of progress notification information, for example, it ispossible to display the ratio by a numerical value (%) or a circlegraph.

Furthermore, FIGS. 21A to 21D show examples in which the whole number ofthe multi-view image becoming the target of the composition processingis the denominator, but when the number of the denominator is great, therouging is performed, and the numerical number after the rouging is setas the denominator, whereby the state of progress notificationinformation may be displayed. For example, when the denominator is 100,the denominator can be displayed as 10 by performing the rouging. Inthis case, the value of the numerator is also changed depending on therouging.

Operation Example of Imaging Device

FIG. 22 is a flow chart that shows an example of the processing sequenceof the multi-view image recording processing by the imaging device 100in the first embodiment of the invention.

Firstly, it is decided whether or not the recoding instruction operationof the multi-view image is performed (step S901), and, when therecording instruction operation is not performed, the monitoring iscontinuously performed. On the other hand, when the recordinginstruction operation is performed (step S901), the captured imagerecording processing is performed (step S910). The captured imagerecording processing will be described in detail with reference to FIG.23. In addition, step S910 is an example of the imaging sequencedescribed in the claims.

Next, a representative image determination processing is performed (stepS920). The representative image determination processing will bedescribed in detail with reference to FIG. 24. Next, a progress barcalculation processing is performed (step S930). The progress barcalculation processing will be described in detail with reference toFIG. 25.

Next, it is decided whether or not the multi-view image is displayed onthe display portion 285 (step S902), and, when the multi-view image isdisplayed on the display portion 285, a view j image creation processingis performed (step S950). The view j image creation processing will bedescribed in detail with reference to FIG. 27. On the other hand, whenthe multi-view image is not displayed on the display portion 285 (stepS902), the representative image creation processing is performed (stepS940). The representative image creation processing will be described indetail with reference to FIG. 26. In addition, steps S940 and S950 arean example of the composition sequence described in the claims.

Next, the display control portion 280 converts the resolution of therepresentative image created by the composition portion 270 to thedisplay purpose (step S903) and displays the representative image of thedisplay purpose with the resolution thereof changed on the displayportion 285 (step S904). In addition, the step S904 is an example of thecontrol sequence described in the claims.

Furthermore, after the view j image creation processing is performed(step S950), the recording control portion 290 records a plurality ofmulti-view images created by the view j image creation processing in thecontent memory unit 300 as the MP file (step S905).

FIG. 23 is a flow chart hat shows an example of the captured imagerecording processing (the processing sequence of step S910 shown in FIG.22) among the processing sequence of the multi-view image recordingprocessing by the imaging device 100 in the first embodiment of theinvention.

Firstly, the imaging portion 240 creates the captured image (step S911)and sequentially records the created captured image on the capturedimage maintenance portion 250 (step S912). Next, it is decided whetheror not the instruction operation of imaging operation end is performed(step S913), and, when the instruction operation of the imagingoperation end is performed, the operation of the captured imagerecording processing is finished. On the other hand, when theinstruction operation of the imaging operation end is not performed(step S913), the process returns to step S911.

FIG. 24 is a flow chart that shows an example of the representativeimage determination processing (the processing sequence of step S920shown in FIG. 22) among the processing sequence of the multi-view imagerecording processing of the imaging device 100 in the first embodimentof the invention.

Firstly, the capturing mode set by the user operation is acquired (stepS921). Moreover, it is decided whether or not two view image capturingmode is set (step S922), and, when the two view image capturing mode isset, the control portion 230 determines the left view image as therepresentative image (step S923).

On the other hand, when the two view image capturing mode is not set(that is, when the multi-view image capturing mode of three view or moreis set) (step S922), the control portion 230 acquires the view number ofthe set multi-view image capturing mode (step S924). Next, it is decidedwhether or not the acquired view number is an odd number (step S925),and, when the acquired view number is the odd number, the controlportion 230 determines the middle image as the representative image(step S926).

On the other hand, when the acquired view number is an even number (stepS925), the control portion 230 determines the left image among twoimages near the middle as the representative image (step S927).

FIG. 25 is a flow chart that shows a progress bar calculation processing(the processing sequence of step S930 shown in FIG. 22) among theprocessing sequences of the multi-view image recording processing by theimaging device 100 of the first embodiment of the invention.

Firstly, the control portion 230 acquires the view number of the setmulti-view image capturing mode (step S931) and acquires the recordingtime per one view (step S932). Next, the control portion 230 calculatesthe recording time of the whole view numbers based on the acquired viewnumber and the recording time per one view (step S933).

Next, it is decided whether or not the recording time of the wholecalculated view numbers is equal to or greater than a regulated time(step S934). When the recording time of the whole calculated view numberis equal to or greater than a regulated time (step S934), the controlportion 230 calculates the display area of the progress bar based on theacquired view number (step S935). In this case, for example, when thenumber of the multi-view image becoming the composition target is great,the plurality of multi-view image is set as one unit, and whenever thecomposition processing of the respective multi-view images correspondingto the respective units is finished, the setting is performed in whichthe display state of the progress bar is changed. Next, the displaycontrol portion 280 displays the progress bar on the display portion 285(step S936).

Furthermore, when the recording time of the whole calculated view numberis less than the regulated value (step S934), the control portion 230determines that the progress bar is not displayed (step S937). In thiscase, the progress bar is not displayed on the display portion 285.

FIG. 26 is a flow chart that shows an example of a representative imagecreation processing (the processing sequence of step S940 shown in FIG.22) among the processing sequence of the multi-view image recordingprocessing by the imaging device 100 in the first embodiment of theinvention.

Firstly, the composition portion 270 calculates the position and thesize of the take-out area (the elongated area) in the respectivecaptured images maintained in the captured image maintenance portion 250based on the interpretation result output from the control portion 230(step S941). Next, the composition portion 270 acquires the elongatedimage from the respective captured images maintained in the capturedimage maintenance portion 250 based on the position and the size of thecalculated take-out area (step S942).

Next, the composition portion 270 composes the elongated image acquiredfrom the respective captured images to create the representative image(step S943). In this case, the composition portion 270 composes theacquired image in an overlapped manner based on the movement amount andthe movement direction output from the movement amount detection portion260 to create the representative image.

Next, the composition portion 270 converts the created representativeimage to the recording resolution (step S944), and acquires the viewnumber of the representative image in which the composition processingis finished (step S945). Next, it is decided whether or not the renewalof the progress bar is necessary (step S946). For example, when asetting is performed in which the plurality of multi-view images is setas one unit and the display state of the progress bar is changed, duringthe time until the composition processing of the respective multi-viewimages corresponding to the respective units is finished, it is decidedthat the renewal of the progress bar is unnecessary. Moreover, when therenewal of the progress bar is necessary (step S946), the displaycontrol portion 280 changes the display state of the progress bar (stepS947), and the operation of the representative image creation processingis finished. On the other hand, when the renewal of the progress bar isunnecessary (step S946), the operation of the representative imagecreation processing is finished.

FIG. 27 is a flow chart that shows an example of a view j image creationprocessing (the processing sequence of step S950 shown in FIG. 22) amongthe processing sequence of the multi-view image recording processing bythe imaging device 100 in the first embodiment of the invention.

Firstly, j=1 (step S951). Next, the composition portion 270 calculatesan elongated position shifting amount β using the size of the take-outarea (the elongated area) calculated in step S941 (step S952). Next, thecomposition portion 270 calculates a shifting amount (e.g., MQj shown inequation 5) of the view j using the calculated elongated positionshifting amount β (step S953).

Next, the composition portion 270 acquires the elongated image from therespective captured image maintained in the captured image maintenanceportion 250 based on the shifting amount of the calculated view j, andthe position and the size of the take-out area (step S954).

Next, the composition portion 270 composes the elongated image acquiredfrom the respective captured images to create the view j image (themulti-view image) (step S955). In this case, the composition portion 270composes the acquired images in an overlapped manner to created the viewj image based on the movement amount and the movement direction that areoutput from the movement amount detection portion 260.

Next, the composition portion 270 convert the created view j image tothe recording resolution (step S956), and acquires the view number ofthe view j image in which the composition processing is finished (stepS957). Next, it is decided whether or not the renewal of the progressbar is necessary (step S958), and, when the renewal of the progress baris necessary, the display control portion 280 changes the display stateof the progress bar (step S959). Meanwhile, when the renewal of theprogress bar is unnecessary (step S958), the process progresses to stepS960.

Next, the recording control portion 290 encodes the view j image inwhich the resolution is changed (step S960) and records the encoded viewj image on the MP file (step S961). Next, it is decided whether or notthe view j is the final view (step S962), and, when the view j is thefinal view, the operation of the view j image creation processing isperformed. On the other hand, when the view j is not the final view(step S962), j is incremented (step S963), and it is decided whether ornot the view j image is the representative image (step S964). When theview j image is the representative image (step S964), the processreturns to step S960, and, when the view j image is not therepresentative image, the process returns to step S953.

2. Second Embodiment

In the first embodiment of the invention, an example has been shown inwhich the plurality of images created by a series of imaging operationsis displayed based on a predetermined rule. Herein, when the multi-viewimage which is created by the imaging operation after the imagingoperation of the multi-view image in the multi-view image capturing modeis finished, it is supposed that a user desires the display of themulti-view image of a particular point of time. Thus, in the secondembodiment of the invention, an example is shown in which, after theimaging operation of the multi-view image is finished, the imagebecoming the display target is changed depending on the posture of theimaging device and is displayed. In addition, the configuration of theimaging device in the second embodiment of the invention isapproximately the same as the examples shown in FIGS. 1 and 11 exceptthat an input and output panel 710 is provided instead of the LCD 172.For that reason, the portions common to the first embodiment of theinvention will be denoted by the identical reference numerals and a partof the description thereof will be omitted.

Exterior Configuration Example of Imaging Device and Using ExampleThereof

FIGS. 28A and 28B are a diagram that shows an exterior configurationexample of an imaging device 700 in the second embodiment of theinvention and an example of the posture at the time of using thereof.The imaging device 700 includes an input and output panel 710.

The input and output panel 710 displays various images and receives theoperation input from a user by detecting the contact operation in theinput and output panel 710. That is, the input and output panel 710includes a touch panel, and the touch panel is, for example, disposed onthe display panel in an overlapped manner so as to transmit the screenof the display panel, and receives the operation input from a user bydetecting the object coming into contact with the display surface.

In addition, the imaging device 700 includes another operation membersuch as an electric power switch and a mode switch-over switch, a lensportion or the like, but for the convenience of description, showing anddescription thereof will be omitted. Furthermore, a part of the opticalunit 112 is built in the imaging device 700.

FIG. 28A shows an example of the posture of the imaging device 700 whenthe review-display of the multi-view image is performed using theimaging device 700. For example, when a person 800 displays themulti-view image using the imaging device 700 after the end of theimaging operation of the multi-view image, the person 800 can see theimage displayed on the input and output panel 710 in the state ofgrasping the imaging device 700 with both hands.

FIG. 28B shows a transition example when the posture of the imagingdevice 700 is changed. FIG. 28B is an example which simply shows a casewhere the state shown in FIG. 28A is viewed from the upper surface.

Herein, a change in posture of the imaging device 700 will be described.For example, a user can change a rotation angle around the intersectingthree axes (i.e., a yaw angle, a pitch angle, and a roll angle) in thestate of grasping the imaging device 700 with both hands. For example,in the state of the imaging device 700 shown in FIG. 28B, the posture ofthe imaging device 700 can be changed (a change in yaw angle) in anarrow direction 701 which sets the vertical direction as an axis.Furthermore, for example, in the state of the imaging device 700 shownin FIG. 28B, the posture of the imaging device 700 can be changed (achange in pitch angle) in the rotation direction which sets thehorizontal direction as an axis. Furthermore, for example, in the stateof the imaging device 700 shown in FIG. 28B, the posture of the imagingdevice 700 can be changed (a change in roll angle) in a rotation arrowdirection which sets the front to rear direction of the person 800 as anaxis.

In addition, in the second embodiment of the invention, an example isshown in which, by changing the posture of the imaging device 700 asshown in FIG. 28B, the image review-displayed on the input and outputpanel 710 is sequentially changed. That is, an example is shown in whichthe image review displayed on the input and output panel 710 issequentially changed by the gesture operation by a user.

Relation Example to Rotation Angle

FIGS. 29A and 29B schematically show a relationship between a pluralityof multi-view images created using the imaging device 700 in the secondembodiment of the invention and a slop angle of the imaging device 700when they are review displayed. In the example, a case will be explainedwhere the multi-view image of five views is created as an example.

FIG. 29A simply shows the plurality of multi-view images (view 1 to view5) created using the imaging device 700.

FIG. 29B shows a transition example of the imaging device 700 when therespective multi-view images are review-displayed after the imagingoperation of the plurality of multi-view images (view 1 to view 5) shownin FIG. 29A is finished. FIG. 29B shows an exterior of a bottom surface(that is, a surface opposite to the surface on which the shutter button183 is provided) of the imaging device 700.

Furthermore, FIG. 29B schematically shows an operation range (the wholerange (angle V) of the rotation angle) of the imaging device 700corresponding to the transition of the imaging device 700. In addition,preferably, the angle V is an angle by which a user can see the displayscreen, and the angle can be 180°.

Furthermore, FIG. 29B shows an example in which the display state of themulti-view image is changed by rotating the imaging device 700 in thearrow 701 direction shown in FIG. 28B to change the posture. A tiltangle (a standard angle), which becomes the standard upon changing thedisplay state of the multi-view image in this case, is represented by γ.The tilt angle γ may be suitably set depending on the number of themulti-view image and may be set by the user operation depending on thepreference of a user. The tilt angle γ can be, for example, 45°.

Furthermore, the multi-view image (view 1 to view 5) shown in FIG. 29Aand the imaging device 700 (the imaging device 700 of the sloped states731 to 735 in the tilt angle γ unit) shown in FIG. 29B are shown so asto be connected by arrows and related to each other. In this manner, thecreated multi-view images (views 1 to 5) are suitably divided in therespective state of tilting by the tilt angle γ unit. In addition, theoperation, in which the display state of the multi-view image is changedby tilting the imaging device 700, will be described in detail withreference to FIG. 30.

FIG. 30 is a diagram that shows a display transition example of theimage displayed on the input and output panel 710 in the secondembodiment of the invention. FIG. 30A shows a display example of theinput and output panel 710 immediately after the imaging operation ofthe multi-view image (view 1 to view 5) shown in FIG. 29A is finished.For example, as shown in the first embodiment of the invention,immediately after the imaging operation of the multi-view image (view 1to view 5) is finished, the multi-view image of the view 3 is displayedon the input and output panel 710 as the representative image.

On the display screen shown in FIG. 30A, the multi-view image of theview 3 is displayed, and a determination button 751, a retake button752, an operational support information 753 and 754, and a message 755are displayed so as to be overlapped with the multi-view image. Inaddition, the multi-view images, which are displayed on the displayscreen shown in FIGS. 30A and 30B, are simply shown by putting thecorresponding characters in parenthesis.

The determination button 751 is a button which is pressed down when themulti-view image (the representative image candidate) displayed on theinput and output panel 710 is newly determined as the representativeimage. That is when the determination button 751 is pressed down, themulti-view image displayed on the input and output panel 710 at the timeof press-down operation is determined as the representative image.Moreover, the recording control portion 290 relates to therepresentative image information showing the determined representativeimage and the sequence relationship (e.g., the view number) of themulti-view image to the created multi-view image and records themulti-view image on the recording medium as the MP file.

The retake button 752 is, for example, a button which is pressed downwhen the imaging operation of the multi-view image is newly performed.That is, after confirming the multi-view image displayed on the inputand output panel 710, when a user decides whether there is a necessityto perform the retaking of the multi-view image, by pushing down theretake button 752, the retaking can be rapidly performed.

The operational support information 753 and 754 is an operation guidefor supporting the operation for changing the multi-view image that isdisplayed on the input and output panel 710. The message 755 is anoperation guide for supporting the operation thereof and thedetermination operation of the representative image.

FIG. 30B shows a display example of the input and output panel 710 whenthe person 800 tilts the imaging device 700 to the right side by anangle greater than or equal to the tilt angle γ from the state shown inFIG. 30A.

For example, as shown in FIG. 30A, in the state in which the multi-viewimage of three views is review-displayed on the input and output panel710, it is considered that the person 800 desires the display of anothermulti-view image. For example, in the state in which the multi-viewimage of the view 3 is review-displayed on the input and output panel710, when the person 800 tilts the imaging device 700 to the right sideby an angle greater than or equal to the tilt angle γ, as shown in FIG.30B, the multi-view image of the view 4 is review-displayed on the inputand output panel 710. Moreover, for example, in the state in which themulti-view image of the view 4 is review-displayed on the input andoutput panel 710, when the person 800 tilts the imaging device 700 tothe right side by an angle greater than or equal to the tilt angle γ,the multi-view image of the view 5 is review-displayed on the input andoutput panel 710.

Furthermore, for example, in the state in which the multi-view image ofthe view 3 is review-displayed on the input and output panel 710, whenthe person 800 tilts the imaging device 700 to the left side by an anglegreater than or equal to the tilt angle γ, the multi-view image of theview 2 is review-displayed on the input and output panel 710. Moreover,for example, in the state in which the multi-view image of the view 2 isreview-displayed on the input and output panel 710, when the person 800tilts the imaging device 700 to the left side by an angle greater thanor equal to the tilt angle γ, the multi-view image of the view 1 isreview-displayed on the input and output panel 710. In this manner, itis possible to review-display the multi-view image other than therepresentative image on the input and output panel 710 as therepresentative image candidate by the operation of tilting the imagingdevice 700.

Furthermore, in the state in which the representative image candidate isreview-displayed on the input and output panel 710 by the operation oftilting the imaging device 700, when the determination button 751 ispressed down, the representative image candidate is determined as a newrepresentative image. For example, in the state in which the multi-viewimage of the view 2 is review-displayed on the input and output panel710 by the operation of tilting the imaging device 700, when thedetermination button 751 is pressed down, instead of the multi-viewimage of the view 3, the multi-view image of the view 2 is determined asa new representative image.

Herein, in the state in which the multi-view image of the view 3 isreview-displayed on the input and output panel 710, when the person 800tilts the imaging device 700 in any direction by an angle greater thanor equal to the tilt angle γ, another multi-view image isreview-displayed. In this case, it is supposed that the compositionportion 270 does not finish the composition processing of the multi-viewimage becoming the display target. Thus, when the display target imageis changed by the operation of tilting the imaging device 700, in a casewhere the composition processing of the multi-view image becoming thedisplay target is not finished, the composition processing of themulti-view image becoming the display target is performed in preferenceto other multi-view images. That is, when the change of the displaytarget image is not performed by the operation of tilting the imagingdevice 700, the composition processing is sequentially performed in thesame sequence as the first embodiment of the invention. On the otherhand, when the display target image is changed by the operation oftilting the imaging device 700 and the composition processing of themulti-view image becoming the display target is finished, thecomposition portion 270 preferentially performs the compositionprocessing of the multi-view image becoming the display target.

As a result, a user can easily and rapidly review-display a desiredmulti-view image depending on the tilt of the imaging device 700. Forthis reason, when a user confirms the multi-view image, it is possibleto easily perform the confirmation. Furthermore, by pressing down thedetermination button 751, a desired multi-view image can be determinedas the representative image.

In addition, the examples shown in FIGS. 30A and 30B show displayexamples in which the display of the progress bar is omitted, but theprogress bar may be displayed simultaneously with the multi-view image.In this manner, an example, in which the multi-view image and theprogress bar are displayed, is shown in FIGS. 31A and 31B.

FIGS. 31A and 31B are diagrams that show display transition examplesdisplayed on the input and output panel 710 in the second embodiment ofthe invention. FIGS. 31A and 31B are examples in which a progress bar756 is provided on the respective display screens shown in FIGS. 30A and30B and are the same as the examples shown in FIGS. 30A and 30B exceptthat another progress bar 756 is provided. In addition, a change indisplay state in the progress bar 756 or the like is the same as thedisplay state in the first embodiment of the invention.

That is, the posture detection portion 220 detects a change in postureof the imaging device 700 based on the posture of the imaging device 700when the representative image is displayed on the input and output panel710. Moreover, the control portion 230 performs a control whichsequentially displays the multi-view image (the representative imagecandidate) on the input and output panel 710 based on the detectedposture change and a predetermined rule after displaying therepresentative image on the input and output panel 710. Herein, thepredetermined rule means, for example, the relation of the multi-viewimage (views 1 to 5) shown in FIG. 29A and the states 731 to 735 (states731 to 735 tilted by the tilt angle γ unit) shown in FIG. 29B.

In addition, the second embodiment of the invention shows an example inwhich the representative image is initially displayed on the input andoutput panel 710, but the multi-view image to be initially displayed maybe determined based on a change in posture immediately after thecreation processing of the plurality of captured images by the imagingportion 240 is finished. That is, the posture detection portion 220detects the change in posture of the imaging device 700 based on theposture of the imaging device 700 immediately after the creationprocessing of the plurality of captured images by the imaging portion240 is finished. Moreover, the control portion 230 may display themulti-view image corresponding to the sequence (the view) depending onthe change of the detected posture on the input and output panel 710 asthe representative image. In this case, when the composition processingof the multi-view image becoming the display target is not finished, thecomposition portion 270 preferentially performs the compositionprocessing of the multi-view image becoming the display target.

Furthermore, the second embodiment of the invention shows an examplewhich uses the operation method of tilting the imaging device 700 as theoperation method for displaying the representative image candidate, butthe representative image candidate may be displayed using an operationmember such as a key button.

Moreover, the second embodiment of the invention showed an example inwhich the representative image candidate is displayed by the useroperation to determine the representative image. However, as shown inthe first embodiment of the invention, when the multi-view image isautomatically and sequentially displayed, the representative image maybe determined from the displayed multi-view image by the user operation.In this case, for example, when a desired multi-view image is displayed,the determination of the representative image can be performed by thedetermination operation using an operation member such as adetermination button.

Operation Example of Imaging Device

FIGS. 32 and 33 are flow charts that show an example of the processingsequence of the multi-view image recording processing by the imagingdevice 700 in the second embodiment of the invention. The processingsequence is a modified example of FIG. 27 (the processing sequence ofstep S950 shown in FIG. 22). For this reason, the same processingsequences as those shown in FIG. 27 are denoted by the same referencenumerals and the description of the common portion will be omitted.Furthermore, the processing sequence shows an example in which therepresentative image is determined by the user operation from themulti-view image that is automatically and sequentially displayed.

After the encoded view j image is recorded on the MP file (step S961),the display control portion 280 converts the resolution of the view jimage created by the composition portion 270 to the display purpose(step S971). Next, the display control portion 280 displays the displayview j image, in which the resolution is converted, on the displayportion 285 (step S972).

Next, it is decided whether or not the determination operation of therepresentative image is performed (step S973), and when thedetermination operation of the representative image is performed, thecontrol portion 230 determines the view j image displayed on the displayportion 285 as a new representative image (step S974). On the otherhand, when the determination operation of the representative image isnot performed (step S973), the process progresses to step S962.

FIGS. 34 and 35 are flow charts that show an example of the processingsequence of the multi-view image recording processing by the imagingdevice 700 of the second embodiment of the invention. The processingsequence is a modified example of FIGS. 32 and 33 (the processingsequence of step S950 shown in FIG. 22). For this reason, the sameprocessing sequences as those shown in FIGS. 32 and 33 are denoted bythe same reference numerals and the description of the common portionwill be omitted. Furthermore, the processing sequence shows an examplein which the representative image candidate is displayed by the useroperation to determine the representative image.

After the elongated position shifting amount β is calculated (stepS952), it is decided whether or not the posture of the imaging device700 is changed by more than a certain amount (step S981), and, when theposture of the imaging device 700 is not changed by more than a certainamount, the process progresses to step S985. Meanwhile, when the postureof the imaging device 700 is changed by more than a certain amount (stepS981), the view j corresponding to the change is set (step S982). Next,it is decided whether or not the composition processing of themulti-view image of the view j is completed (step S983), and, when thecomposition processing of the multi-view image of the view j iscompleted, it is decided whether or not the recording processing of themulti-view image of the view j is completed (step S984). Herein, a case,where the composition processing of the multi-view image of the view jis completed, is, for example, a case where, in regard to the view jimage (the multi-view image) created by the composition of the elongatedimage, the recording resolution conversion is not performed (e.g., theview j image (the final image) 420 shown in FIG. 9). Furthermore, a casewhere, the recording processing of the multi-view image of the view j iscompleted, is, for example, a case where the encoded view j image (themulti-view image) is recorded on the MP file (e.g., a case of beingrecorded on the MP file shown in FIG. 9).

Furthermore, when the composition processing of the multi-view image ofthe view j is completed (step S938), the process progresses to stepS953. Furthermore, when the recording processing of the multi-view imageof the view j is completed (step S984), the process progresses to stepS971, and, when the recording processing of the multi-view image of theview j is not completed, the process progresses to step S985.

Moreover, in step S985, it is decided whether or not the recordingprocessing of a view (j-1) image is completed, and, when the recordingprocessing of the view (j-1) image is completed, the process progressesto step S960. On the other hand, when the recording processing of theview (j-1) image is not completed (step S985), the process progresses tostep S971.

Moreover, when the posture of the imaging device 700 is not changed bymore than a certain amount (step S981), j=0 ((step S986), and j isincremented (step S987). Next, it is decided whether or not thecomposition processing of the multi-view image of the view j iscompleted (step S988), and when the composition processing of themulti-view image of the view j is completed, it is decided whether ornot the recording processing of the multi-view image of the view j iscompleted (step S989). When the recording processing of the multi-viewimage of the view j is completed (step S989), the process returns tostep S987, and when the recording processing of the multi-view image ofthe view j is not completed, the process returns to step S985. Moreover,when the composition processing of the multi-view image of the view j isnot completed (step S988), the process returns to step S953.

Furthermore, when the recording processing of the multi-view image iscompletely finished (step S990), the operation of the view j imagecreation processing is finished. Meanwhile, when the recordingprocessing of the multi-view image is not completely finished (stepS990), the process returns to step S981.

In addition, in the embodiment of the invention, an example has beenshown of the display example of the review display in a case where themulti-view image is created using the plurality of captured images thatcontinue in the time series. However, when the continuous image iscreated using the plurality of captured images that continues in thetime series, the embodiment of the invention can be applied to a casewhere the review-display is performed in regard to the continuous image.For example, when the continuous mode is set, the imaging portion 240creates the plurality of captured images (e.g., 15 sheets) thatcontinues in the time series. Moreover, the recording control portion290 gives at least a part (or the whole) among the plurality of createdcaptured images a sequence relationship based on a predetermined rule,relates them to each other, and records them on the content memory unit300. That is, the plurality of captured images that continues in thetime series is given with the sequence relationship depending on thecreation sequence thereof, is related to each other, and recorded as theimage file of the continuous image. In this case, the control portion230 performs a control which displays the captured image (e.g., theimage (the seventh image) of the right center) becoming a predeterminedsequence among the plurality of captured images becoming the recordingtarget on the display portion 285 as the representative image, after thecreation processing of the plurality of captured images by the imagingportion 240 is finished.

Furthermore, the invention can be applied to an imaging device such as amobile phone having an imaging function or a portable terminal devicehaving an imaging function.

Moreover, the processes and functions described above may be implementedin a distributed or “cloud” computing environment in which theprocessing responsibilities are distributed among a plurality ofprocessing devices. For example, the image data may be acquired at theimaging device, then transferred over a network, or other connection, toanother processing device, which performs the processing steps describedabove to create the composite images. The composite images may then betransferred back to the imaging device, or to another processing device,which could then display the composite images. Similarly, the imagingdevice may acquire the image data from another processing device orimaging device, then perform the processing steps described above tocreate the composite images. Various other combinations are possible insuch a distributed computing environment, and the present disclosure isnot limited to a configuration in which all of the processing isperformed in a single device, as disclosed in an exemplary embodimentabove.

In addition, the embodiment of the invention shows an example forembodying the invention, as it is apparent from the embodiment of theinvention, the matters in the embodiment of the invention and thespecific matters of the invention in the claims are in the correspondingrelationship, respectively. Similarly, the specific matters of theinvention in the claims and the matter in the embodiment of theinvention having the same name as the former are in the correspondingrelationship, respectively. However, the present invention is notlimited to the embodiment but can be embodied by carrying out variousmodifications of the embodiment within the scope without departing fromthe gist of the invention.

Furthermore, the processing sequence described in the embodiment of theinvention may be understood as a method having the series of sequences,and may be understood as a program for executing the series sequences ina computer and as a recording medium that stores the program. Therecording medium, for example, a CD (Compact Disc), an MD (MiniDisc), aDVD (Digital Versatile Disc), a memory card, a Blu-ray Disc (trade mark)or the like can be used.
